Two‐Dimensional Direction‐of‐Arrival Estimation of Noncircular Signals in Coprime Planar Array with High Degree of Freedom

open access: yesMathematical Problems in Engineering, 2019
In estimating the two‐dimensional (2D) direction‐of‐arrival (DOA) using a coprime planar array, there are problems of the limited degree of freedom (DOF) and high complexity caused by the spectral peak search. We utilize the time‐domain characteristics of signals and present a high DOF algorithm with low complexity based on the noncircular signals. The

Hole Locations and a Filling Method for Coprime Planar Arrays for DOA Estimation [PDF]

open access: yesIEEE Communications Letters, 2021
Coprime linear arrays (CLAs) have drawn lots ofattention. Efforts have been made to reveal the hole locations inthe difference coarrays of CLAs, based on which many methodshave been proposed to fill the holes, lengthening the consecutivedifference coarray part and increasing the effective degreesof freedom (DOFs). Compared with CLAs, two dimensional(2D)

Sparsity-Based Two-Dimensional DOA Estimation for Co-Prime Planar Array via Enhanced Matrix Completion

open access: yesRemote Sensing, 2022
In this paper, the two-dimensional (2-D) direction-of-arrival (DOA) estimation problem is explored for the sum-difference co-array (SDCA) generated by the virtual aperture expansion of co-prime planar arrays (CPPA). Since the SDCA has holes, this usually

Super Nested Arrays: Sparse arrays with Less Mutual Coupling than Nested Arrays [PDF]

open access: yes, 2016
In array processing, mutual coupling between sensors has an adverse effect on the estimation of parameters (e.g., DOA). Sparse arrays, such as nested arrays, coprime arrays, and minimum redundancy arrays (MRAs), have reduced mutual coupling compared to ...
